Abstract

Space debris identification and localization has been studied for a long time at home and abroad, but there are still shortcomings in the detection of very low SNR small targets, especially the detection and recognition of very low SNR faint small targets submerged in the dense galactic background stars. In order to effectively target detection, background removal is essential to distinguish between the target and the stars through the accumulation of judgement block number of stars closely adjacent to judge, if the judgment of the block star is a closely adjacent number more than a set threshold, so that the point for stars, on the other hand, argue that the point as the goal is to be detected, then, to the star point of the block. The results of the algorithm show that, according to different star map images, the size of matrix block and the threshold of star point can be modified to achieve better star removal effect.
